Can liquid wallpaper be applied to drywall? Peculiarities

Today, plasterboard is used for finishing residential premises and technical areas. You can apply various materials to it, including decorative plaster. You can often find the same question on forums: is it possible to apply liquid wallpaper to drywall? The answer is yes - it’s possible, and not only on walls. You can make a plasterboard ceiling using liquid wallpaper.

The article reveals exactly this topic, highlighting the characteristics of the material. Attention is focused on the preparation of sheets, and the technology for preparing and applying liquid wallpaper is revealed.

Features of drywall

Drywall (hereinafter referred to as gypsum board) material itself is almost perfectly smooth. Liquid wallpaper is made on a paper base, so it easily contacts different surfaces, including drywall.

To secure the sheets, special self-tapping screws are used, which can rust over time. You can hide this drawback by treating them with putty. It is advisable to paint it before installation.

Another nuance that you should pay attention to is the high-quality finishing of joints and connections.

Nuances of preparing the base

These procedures are considered mandatory and require a responsible approach to prevent the formation of cracks and corrosion stains:

If the joints of the parts do not have a chamfer or have not been embroidered, then a V-shaped seam is formed. To do this, using a construction knife, trimming is carried out at an angle of 45 degrees on each side. It is taken into account that the recess should not exceed 2/3 of the sheet thickness.
The resulting joints are coated with a deep-penetrating primer. The mixture is applied evenly without excess; it is important to treat all areas.
It is recommended to cover the screw heads with anti-corrosion paint. The procedure is optional, but in this case the possibility of stains is completely eliminated.
A putty solution is prepared and all seams are sealed. If work is carried out in a house or apartment where shrinkage is observed, then reinforcing mesh or tape is additionally used. The material must be glued exactly in the center of the joint, after which the compound must be applied and finally leveled.

The reinforcement of drywall seams cannot be neglected, otherwise, with the slightest movement of the base or poor-quality putty, noticeable cracks will appear along the joints

If the screws have not been painted over, then a putty solution must be applied pointwise to the places where they are buried. Due to the fact that liquid wallpaper adheres well to small uneven surfaces, this measure is aimed at preventing the appearance of rust.
To increase adhesion, the surface is primed. This will prevent peeling that occurs due to contact with fatty substances.

When working with liquid wallpaper, careful grinding of the surface is not necessary, since the wallpaper mixture can level out unevenness with a curvature of up to 1.5 mm.
If it is necessary to protect the surface of the drywall during the subsequent dismantling of the decorative coating, then the base must be puttied completely. The mixture must be applied in a thin, even layer, and after drying, primer must be applied.

Advice! To ensure that the wall is perfect and the shade of the silk plaster does not change over time, the surface is painted white. For these purposes, a water-based composition is used.

Is it possible to apply liquid wallpaper to drywall?

Applying liquid wallpaper to drywall does not contradict technical and environmental standards. This is a dry composition made on the basis of:

Pulp.
Cotton.
Silks.
And their mixtures.

To prepare the working mixture, simply dilute the dry composition with water. The manufacturer indicates the proportions and preparation technology on the outside of the packaging material. Any type of liquid wallpaper has its own unique advantages and can be used in any office or residential premises, including children's rooms.

Can silk plaster be applied to drywall?

When working with surfaces made from gypsum board sheets, a problem arises when it is necessary to determine the correct method of laying the material. The fact is that the base does not always have good adhesion to the selected product. But when using liquid wallpaper, whose second name is “silk plaster,” for finishing, such difficulties do not arise.

The technology for applying this material involves two methods. They have some differences, but are equally effective:

Full putty. This process involves pre-finishing the entire drywall surface. The resulting layer has good adhesion and greatly facilitates the procedure for dismantling the decorative coating, if necessary in the future.
Installation without putty. This method avoids lengthy surface preparation. Liquid wallpaper on a cellulose or cotton basis is perfectly applied to cardboard, providing reliable adhesion, but if it is necessary to remove the decorative layer, a lot of problems will arise. The fact is that the adhesion between the material and the top coating of gypsum board sheets is very high, so it will be impossible to remove the cladding without damaging the boards.

Home craftsmen mistakenly think that penetrating primer paint can replace putty; in fact, this material is intended for other purposes.
Silk plaster is excellent for finishing plasterboard surfaces, provided the correct technology is chosen.

Preparing drywall

To prepare both gypsum board and liquid wallpaper, you must first decide on the working tool. To work you will need:

There are two types of spatulas for working with putty: narrow and wide.
For applying primer and paint - rollers and brushes.
To level the surface you need sandpaper or a grinding machine.
To mix the dry composition with water, you need to prepare a drill with a mixer.
Don’t forget about a container, preferably a plastic bucket.

That's not all:

Need putty.
Serpyanka mesh.
Primer.
White paint.

Having finished preparing the tools and materials, you can begin the preparatory process, following a certain sequence.

Initially, it is necessary to clean the surface of debris and dust.
Check the fasteners by running your hand over the sheet. Pay special attention to the places where the screws are attached. If they protrude, push them down using a screwdriver.
Sheet joints must have an edge. If it is not there, you can use a construction knife to make it by cutting the joints at an angle of 450.
Putty the joints and fastening points with putty, after gluing them with sickle mesh. This will prevent microscopic cracks that can form over time.

When the putty has dried, sanding is done with sandpaper. After this, it is necessary to clean the work surface from any dust that has formed.
Then, completely cover the sheet with putty, using a wide spatula. Allow the putty to dry for a certain time and sand it with sanding paper secured to a wooden block.
Apply primer to the drywall using a roller. Treat hard-to-reach areas with a brush. To cover the walls, you can add 10% PVA glue to the ground, which will give the liquid wallpaper hardness and additional resistance to moisture.

Experts recommend painting the HA sheet white. The paint should be applied in two stages. After preparing the gypsum board, you can cover it with liquid wallpaper.

Preparing the plasterboard base

Liquid wallpaper is ideal for treating plasterboard walls due to its excellent compatibility with this type of material. Preparing drywall before applying liquid wallpaper is not particularly difficult and will take very little time.

First of all, the sheets should be installed and secured, and then you can begin to treat the surface.

Sealing joints, seams, holes

You should start by priming the entire surface, filling the pores. Coating with a primer mixture will facilitate the process of puttying joints and further leveling the plaster. Then check whether the fastening screws are protruding. If necessary, protruding screw heads should be tightened more firmly, deepening them flush with the surface, and coated with paint to avoid corrosion.

When preparing drywall for covering it with liquid wallpaper, it is necessary to apply a primer, as well as standard putty, working out the joints and screws.

Before sealing the seams, small indentations must be made in the joints between the sheets. To do this, an incision 2–3 mm deep is made at an angle of 45 degrees on both sides of the connection line, which is then filled with putty and covered with reinforcing mesh. The tape is placed strictly in the center of the seam, preferably capturing the screw heads. Then, using a spatula, press the strip into the solution so that there are no unfilled areas left. The remaining mixture is collected with a spatula and carefully leveled.

Advice. When applying plaster, do not leave lumps, drops or other irregularities. Once dry, it will be much more difficult to get rid of them.

Plastering and leveling surfaces

After all joints and seams are securely sealed, some experts recommend covering the entire surface of the gypsum board with a thin layer of plaster. This will serve as additional protection for the sheet, and will also subsequently simplify the replacement of the wall finish.

After the plaster has hardened, you need to walk over the surface with a sanding block to completely level it and remove roughness. Finally, remove dust with a brush or slightly damp cloth.

The final stage of preparation

Before directly applying liquid wallpaper, drywall should be coated with another layer of primer.

You can also pre-paint the prepared plasterboard surfaces before applying the liquid layer of wallpaper. This is not a fundamentally important stage, however, for better color rendition and to avoid the appearance of dark spots, it is better to cover the plastered surface with white paint.

After the plaster and paint have completely dried, you can apply liquid wallpaper to the drywall.

Preparation and application of liquid wallpaper

The next stage includes preparation and subsequent application of liquid wallpaper onto the gypsum board sheet. The preparation process is not complicated. The necessary information is on the outside of the package. Before applying liquid wallpaper to drywall, you need to prepare the composition. You should take an 8-liter plastic container and dilute the dry mixture with water. It is advisable to mix by hand.

On a note!
One bag of dry mixture requires 6-7 liters of water t0 30-350C.

The finished composition, like cognac, requires aging. This may take from 2 to 8 hours. It all depends on the manufacturer of the dry mixture.

For your information!
The finished mixture can be stored and used for 3-5 days at t0 about 200C.

The mixture is taken with a spatula and spread on a plastic grater, with which a layer is applied. Work should start from the corner, which will ensure uniform distribution of the decorative composition. Circular movements should be free and natural. When the surface of the drywall is completely processed, it takes time for the applied mixture to dry. This may take 24 to 48 hours. It all depends on the manufacturer's recommendations.

This might come in handy!
If you find any flaws, don't worry. The composition does not dry out immediately. Therefore, the problem is easy to fix.

Preparation of liquid wallpaper: features of the process

Before you prepare liquid wallpaper for work, you need to figure out exactly the entire sequence of the main stages.

A certain amount of dry mixture is poured into a container with warm (not hot!) water. For details about the proportions, see the packaging: the consumption of dry matter, as well as data on calculating its use, should be contained in the instructions.
Then the entire solution must be mixed well and left to completely dissolve for approximately several hours and covered tightly with a lid.

Attention! It is necessary to mix in such a way that there are no lumps in the solution. If possible, it is better to mix by hand. The mixture, carefully prepared and covered with a lid, can be stored for up to five days, at an average temperature of about 20 degrees.

How to apply

For each individual wall, you should try to use a separate batch of mortar. Then the prepared wallpaper will be enough to apply from corner to corner. Otherwise, the edges will dry out differently, and unsightly joints will form between them. And no amount of putty will help.

Advice! There is also a certain way for those who need to get rid of dry liquid wallpaper. Wet the edge in the liquid. We do this until the moisture is completely “drawn in”. After this, the area can be smoothed using a plastic grater.

This type of work can easily be done by one person without outside help. Liquid wallpaper is applied in a uniform layer, which should not exceed 5-7 mm. Small irregularities and roughness are hidden “automatically”.

How to properly apply liquid wallpaper to drywall is shown in the video:

There are other important application rules:

to glue wallpaper on walls, movements must be circular;
no need to spend a lot of time smoothing the same area. Several approaches are enough, otherwise the silk fibers roll into balls and change their appearance;
We pay special attention to the thickness of the material. A few millimeters are enough to get a smooth surface without defects. Otherwise, the material consumption will increase and will not be justified. The same goes for putty;
Wallpaper usually takes at least 48 hours to dry. The microclimate in the room contributes to changing this parameter.

Liquid wallpaper goes well with drywall if you take care of the preliminary preparation: puttying and priming. It is not at all difficult to work with such decorative materials. The environmental friendliness of liquid wallpaper makes it more and more popular every year. They can leave few people indifferent. The variety of available colors is also appreciated.

Can i ask you? What should you do if you applied liquid wallpaper to drywall and applied plaster only to the joints? There is a primer, but it is naturally more transparent. As a result, all the joints, this wide strip, are visible under the wallpaper. Is there no way to save the situation?

How to apply liquid wallpaper yourself

For walls in new houses that have not yet undergone shrinkage, such repairs are not recommended. It is also important that all slopes and doors are already in order. The workflow consists of three stages. The first one is very important, you can’t skip it if you don’t want to redo the repair.

Do-it-yourself wall preparation

Most solutions dry translucent. If there is not a smooth, white background underneath, defects may show through. Therefore, the base, painted in different colors, must be leveled. The wallpaper mixture to some extent levels out the depressions and protrusions, but if they are deep, it is better to seal them first. Otherwise, the material consumption will increase and dark spots will remain after drying.

Remove all old trim, if any.
Coat metal parts with oil paint or anti-corrosion impregnation.
Remove any nails that are too protruding from the surface.
If you are gluing liquid wallpaper onto drywall, cover the seams between the sheets with paper tape or sickle tape. Pre-cut problem areas and prime them.
Then putty the entire wall.
After the surface has dried, prime it once or twice. This will prevent moisture from the solution from being absorbed into the base.

See how to do it correctly and what tools you use in the master class. The builders show the application technique in detail.

Pay attention to the quality of the tape and putty. You can't save money on them. If they peel off or bulge, the finish layer may crack.

Types of liquid wallpaper

There are several types of liquid wallpaper:

Silk. This type creates the effect of fabric wallpaper. They are not subject to burnout and mechanical damage. Therefore, they manifest themselves as one of the most wear-resistant materials;
Cellulose liquid wallpaper. The composition includes components of organic origin - recycled wood (cellulose). This type is cheaper than silk. The density of the material provides sound and heat insulation.
Cellulose liquid wallpaper and the addition of silk. This is a symbiosis of the previous two species. They combine all the most positive features. In addition, this option is suitable for those who do not want to choose between silk and cellulose.

Liquid wallpaper: pros, reviews

Liquid wallpaper has the following advantages:

The absence of joints and seams, convenience when decorating complex and uneven surfaces (arches, openings and protrusions in the interior, areas near sockets and chandelier mounts).
Eco-friendly and hypoallergenic material. As Candidate of Technical Sciences L.V. points out in his article. Wait and A.P. Knurev, the natural components of wallpaper have a neutral charge and do not attract dust particles. This is especially important for people suffering from allergies and asthma.
The ability to visually straighten curved walls. You don't need complex and expensive correction: by choosing wet wallpaper with a relief texture, you can successfully disguise this flaw. A good mood, according to ordinary people, is guaranteed.
They increase heat and sound insulation, the latter is important in apartment buildings. As construction materials and design consultant A.A. notes in his article. Gusevsky, the material has high vapor permeability, which prevents the formation of fungus and mold on the walls.
Liquid wallpaper does not deform when the walls shrink; they can be safely used in fresh new buildings.
The ability to discreetly correct damage to the surface of the wallpaper. To do this, apply a little material to the dampened area of the wall, smooth it with a spatula and let it dry.
